GEB'MIGIDE AND INSECTIGIDE.

No Drawing.

To all whom it may concern:

I -Be it known that I, GUs'rAv FRrrscHE,

a subject of theEmperor of Austria and a resident of Strzebowitz, nearSchiinbrunn, Austria-Hungary, have invented a certain new and usefulGermicide and Insecticide, of which the following is a specification.

I have found that certain mixtures of skimmed milk and formalin havegreat antiseptic as well as germicidal and insecticidal effects. I havefurther found that such mixture is mainly used for medicinal andprophylatic purposes. I have especially obtained very good results byusing such mixtures in cases of inflammatory rheumatism. One of thetheories of the cause of rheumatism" is based on the existence ofcertain microbes which would be killed by the mixtures described. Inusing these mixtures to cure rheumatism they are applied externally inthe form of wet compresses and the like.

When using these mixtures for the preservation of food, for instance,meat, I have found that two cubic centimeters of the same are suflicientfor one liter of water in which the meat is cooked.

When using the mixtures as insecticides I have found that theapplication thereof in the form of a spray is effective.

In preparing these mixtures I proceed as follows: Ten liters of skimmedmilk are heated to the boiling point and kept at same Specification ofLetters Patent.

Patented Uct. 29,1912.

Application filed l'une 28, 1907. Serial No. 381,215.

for forty-five minutes, then the milk is cooled and one liter offormalin is added under stirring. The mixture is then filtered and readyfor use. Of course it is understood that I do not limit myself to theseexact proportions.

What I claim-is as follows:

1. An antiseptic comprising skimmed milk previously heated to theboiling point and cooled and formalin.

2. An antiseptic comprising ten parts of skimmed milk previously heatedto the boil-' ing point and cooled and one part'of formalin. I

8. Ari antiseptic comprising slightly condensed skimmed milk, previouslyheated to the boiling" point and maintained at the boiling point forsome time and then cooled, and formalin.

4. An antiseptic comprising ten parts of slightly condensed skimmedmilk, previously heated to the boiling point and maintained at theboiling point for some time and then cooled, and one part of formalin.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
